Isospectral heterogeneous domains: A numerical study
We have applied the finite differences method to the study of a pair of isospectral heterogeneous domains, first introduced in Ref. [1]. We show that Richardson and Padé-Richardson extrapolations can be used (as in the homogeneous case) to obtain very precise approximations to the lowest eigenvalues...
